Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after five to 10 seconds,
especially in very cold weather
(below −18 °C or 0 °F), it could
be flooded with too much
gasoline. Try pushing the accelerator pedal all the way to
the floor and holding it there as
you hold ENGINE START/
STOP, for up to a maximum of
15 seconds. Wait at least
15 seconds between each try,
to allow the cranking motor to
cool down.
When the engine starts, let go
of the button and the
accelerator. If the vehicle starts
briefly but then stops again,
follow the same steps. This
clears the extra gasoline from
the engine.
Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Engine Heater
Vehicles may have an engine
heater. The engine heater can help
in cold weather conditions at or
below
−18 °C (0 °F) for easier
starting and better fuel economy
during engine warm-up. Plug in the
heater at least four hours before
starting the vehicle. An internal
thermostat in the plug end of the
cord will prevent engine heater
operation at temperatures above
−18 °C (0 °F).
{Warning
Do not plug in the engine block
heater while the vehicle is parked
in a garage or under a carport.
Property damage or personal
injury may result. Always park the
vehicle in a clear open area away
from buildings or structures.

3. Remove the cover on theconsole.
4. Insert and push the key intothe slot. 5. Move the shift lever out of
P (Park). If P (Park) is selected
again after the key is removed
from the slot, the shift lever will
be locked again.
6. Remove the key from the slot.
7. Close the cover.
8. Have the cause of the problem fixed by your dealer.
Parking over Things
That Burn
{Warning
Things that can burn could touch
hot exhaust parts under the
vehicle and ignite. Do not park
over papers, leaves, dry grass,
or other things that can burn.
Extended Parking
It is best not to park with the vehicle
running. If the vehicle is left running,
be sure it will not move and there is
adequate ventilation.
See Shifting Into Park 0156 and
Engine Exhaust 0159.
If the vehicle is left parked and
running with the RKE transmitter
outside the vehicle, it will continue
to run for up to half an hour.
If the vehicle is left parked and
running with the RKE transmitter
inside the vehicle, it will continue to
run for up to an hour.
The vehicle could turn off sooner if it
is parked on a hill, due to lack of
available fuel.
The timer will reset if the vehicle is
taken out of P (Park) while it is
running.

To turn LDW on and off, press@on
the instrument panel to the left of
the steering wheel. The control
indicator will light when LDW is on.
When LDW is on,
@is green if LDW
is available to warn of a lane
departure. If the vehicle crosses a
detected lane marking without using
the turn signal in that direction,
@
changes to amber and flashes.
Additionally, there will be three
beeps on the right or left, depending
on the lane departure direction.
LDW will not alert if the turn signal
is active in the direction of lane
departure, or if LDW detects that
you are accelerating, braking or
actively steering.
When the System Does Not
Seem To Work Properly
The system may not detect lanes as
well when there are:
. Close vehicles ahead.
. Sudden lighting changes, such
as when driving through tunnels.
. Banked roads.
If the LDW system is not functioning
properly when lane markings are
clearly visible, cleaning the
windshield may help.
LDW alerts may occur due to tar
marks, shadows, cracks in the road,
temporary or construction lane
markings, or other road
imperfections. This is normal system
operation; the vehicle does not need
service. Turn LDW off if these
conditions continue.
Fuel
Top Tier Fuel
GM recommends the use of TOP
TIER Detergent Gasoline to keep
the engine clean, reduce engine
deposits, and maintain optimal
vehicle performance. Look for the
TOP TIER Logo or see
www.toptiergas.com for a list of TOP
TIER Detergent Gasoline marketers
and applicable countries.

Recommended Fuel
Use regular unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 87—
(R+M)/2 —or higher. Do not use
gasoline with a posted octane rating
of less than 87, as this may cause
engine knock and will lower fuel
economy.
Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so
may damage the vehicle and void
its warranty:
. For vehicles that are not
FlexFuel, fuel labeled
greater than 15% ethanol by
volume, such as mid-level
ethanol blends (16–50%
ethanol), E85, or FlexFuel.
. Fuel with any amount of
methanol, methylal,
ferrocene, and aniline.
These fuels can corrode
metal fuel system parts or
damage plastic and rubber
parts.
. Fuel containing metals such
as methylcyclopentadienyl
manganese tricarbonyl
(MMT), which can damage
the emissions control
system and spark plugs.
(Continued)
Caution (Continued)
.Fuel with a posted octane
rating of less than the
recommended fuel. Using
this fuel will lower fuel
economy and performance,
and may decrease the life of
the emissions catalyst.
Fuels in Foreign
Countries
The U.S., Canada, and Mexico post
fuel octane ratings in anti-knock
index (AKI). For fuel not to use in a
foreign country, see Prohibited
Fuels 0180.
Fuel Additives
TOP TIER Detergent Gasoline is
highly recommended for use with
your vehicle. If your country does
not have TOP TIER Detergent
Gasoline, add ACDelco Fuel
System Treatment Plus−Gasoline to
the vehicle’ s gasoline fuel tank at
every oil change or 15 000 km

TOP TIER Detergent Gasoline and
ACDelco Fuel System Treatment
Plus−Gasoline will help keep your
vehicle’s engine fuel deposit free
and performing optimally.

{Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.
Follow these guidelines to help
avoid injuries to you and others:
. Read and follow all the
instructions on the fuel
pump island.
. Turn off the engine when
refueling.
(Continued)
Warning (Continued)

unattended.
. Avoid using electronic
devices while refueling.
. Do not re-enter the vehicle
while pumping fuel.
. Keep children away from
the fuel pump and never let
children pump fuel.
. Before touching the fill
nozzle, touch a metallic
object to discharge static
electricity from your body.
. Fuel can spray out if the fill
nozzle is inserted too
quickly. This spray can
happen if the tank is nearly
full, and is more likely in hot
weather. Insert the fill nozzle
slowly and wait for any hiss
noise to stop before
beginning to flow fuel.
To open the fuel door, push and
release the rearward center edge of
the door.
The capless refueling system does
not have a fuel cap. Fully insert and
latch the fill nozzle, begin fueling.
{Warning
Overfilling the fuel tank by more
than three clicks of a standard fill
nozzle may cause:
. Vehicle performance issues,
including engine stalling and
damage to the fuel system.

If a fire starts while you are
refueling, do not remove the fill
nozzle. Shut off the flow of fuel by
shutting off the pump or by
notifying the station attendant.
Leave the area immediately. Filling the Tank with a Portable
Fuel Container
If the vehicle runs out of fuel and
must be filled from a portable fuel
container:
1. Locate the capless funnel
adapter.
2. Insert and latch the funnel into the capless fuel system.
{Warning
Attempting to refuel from a
portable fuel container without
using the funnel adapter may
cause fuel spillage and damage
the capless fuel system. This
could cause a fire. You or others
could be badly burned and the
vehicle could be damaged. 3. Remove and clean the funnel
adapter and return it to the
storage location.
